GEN 2 Belt noise under wide open throttle

[Hdaniel85]

Hey all,

I have what sounds like a bad/loose belt under wide open throttle. When I inspect the belt I don't see any signs of damage/worn out.

It's a 2019 with 8k miles on it. I will try to get a video of it after work, I just noticed it the past couple of days, it idles fine and I don't feel any loss in power.

Around 45000 rpm before 3rd to 4th shift?

Maybe, it is from a rolling start going onto the freeway from an on ramp, here is a video. You have to listen closely but you can hear the noise. I will try to get a better video but thats all I had for now.

Sounds like a slipping serpentine. Take it to the dealer since you’re in warranty. No reason you should have to change the belt yourself. This was happening on my truck at around 30k. Bought a belt and slapped it on. No more noise!
